Specification of Letters Patent.

Application filed May 5, 1914. Serial nasaaess.

To all whom it may concern Be it known that I, VICTOR J. SHEPARD, a citizen of the United States, residing at 119 South Baxter street, Lima, county of Allen, and State of Ohio, have invented certain new and useful Improvements in Radial Trailer-Trucks, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to locomotive engines having auxiliary frame-bars extended backwarclly from the main-frames to support the load at the rear end. In such case, a radial truck is fitted to support the weight upon such auxiliary frame-bars, and means is required for transmitting the load upon such frame through suitable springs to the journalboxes of the radial truck-wheels.

As a radial truck is pivoted to the frame of the locomotive, it is compelled, when moving around curves, to swing to one side or the other of the frame, and as the springs and their equalizers have a fixed relation to the frame, it is necessaryto provide some connection between the bearing-boxes of the radial truck-axle and such springs, which will permit movement of the bearings to different positions under the frame, and at the same time transmit to the springs any Thls 1s vertical motion of the bearings. effected in the present construction through spring-bearing-blocks movable vertically in sockets which are held rigidly by the sideframes, over the journal-bearings of the truck-axle, the foot of each bearing-block upon such load-plate, and maintains its.

bearing thereon when the journal-bearing is tipped out of its normal position.

The spring is preferably supported within the bearing-block by a guide-block having a rocking connection therewith to compensate for the various positions of the spring as the bearing-block is moved up or down in its socket.

The construction will be understood by reference to the annexed drawing, which PatentedJ 1113 28, 1914;.

illustrates one form of the invention, andin 1 which.

'The rear I gdriving wheels F, and theiradialtruckis a perspective view of the bearing-plate. ith spherical boss upon the top to fit a condriving-axle E is shown with at their rear ends by footgframe G is provided wit-h bearings-Hfor Ethe axle I of the truck-wheels J; I The truck-frame G is formed with a ghinge-lug aat its forward end fitted to a gpivot a carried by the cross-tie A, and the rear end of the truck-frame is provided with ia lug K fitted between centering springs L ;in the usual manner, such springs being imounted movably upon theframeB or foot- Eplate D. i

j The truck-wheels J operate outside of the Eauxiliary frame-bars B, and .the truckframe G supports the journal-bearings H loutside of the wheels J To support a semi-elliptic spring H over each bearlng, and to make the desired connection between the springs and the journalbearing, the bearings are furnished each,

as shown in Fig.1 on the top with a fiat load-plate 0, and brackets M are projected (nitwardly from the beams B at opposite sides of the bearings H and carry a bridgebar or beam N, in the middle of which is formed a socket c, as shown in Fig. to carry a'vertically movable springbearmgblock (Z, which, when the truck-frame G is in its central position, stands over the center of the load-plate c. The brackets hi and bars N form a rigid yoke over the journal.

The bearing-block is formed with a foot lettered d in Figs. 2 and 7, and with sidewalls cl fitted to the opposite sides of the socket 0, as shown in Fig. 6.

The base f and the side-walls f are provided at their edges with ribs f which serve to embrace the band or" the spring, as shown in Fig. 3. The base f has upon its under side a segmental cylindrical projection c which is fitted to a transverse recess 6 0-1": similar shape in the upper side of the foot (Z, so that the guide-block has a rocking connection with the bearing-block.

Ribs (Z are formed at the edges of the walls (Z and serve to limit the rocking movement of the guide-block.

The under side of the foot (Z has a spherical recess h, and a bearing-plate c' is formed to rest upon the top of the journal bearing, and is provided with a spherical boss fitted to the recess it.

At opposite sides of the sockets 0 the bridge-bar is provided with openings or recesses O, which receive the lower corners of the spring H and serve to hold the same in its working position.

The bridge-bars are shown with slots 0 through which the links p are extended to connect the ends of the spring H with the bridge-bar and with an equalizing-bar Q, This equalizing-bar is connected in the usual manner by link is with the semi-elliptic spring H over the driving-axle E. The relation of the spring to the bearing-plate i is clearly shown in Fig. 2, where it will be seen that the bearingsblock can tip in any direction upon the bearing-plate z' which rests upon the top of the journal -bearing, as shown in Fig. 1. i

The rocking connection of the springguide-bloek f with the foot (Z of the bearingblock, is also clearly shown, as well as the clearance between the walls f of the guide block and the ribs (Z upon the bearing-block which limit the rocking movement.

The load-plate 0 is provided upon the top of the j ournal-bearing H to furnish an area of width greater than the bearing-plate e, as shown in Fig. 5, so that the bearing plate may retain its contact with the top of the bearing when the radial truck assumes various lateral positions beneath the auxiliary frame-bars B.

Any vertical motion of the journal-bearing is thus transmitted to the spring by the vertically movable bearing-block 62. while move to various springs.

The construction of the parts connected with the spring-bearing-blocks is exceedingly cheap and simple and requires finish only where the bearing-plate rests upon the load-plate of the bearing, and where the boss 7' is fitted to the recess h.

The parts above the journal-bearing may be used in common for engines of different classes, in cases where the truck below requires alteration, thus reducing the numb-er of repair parts which it is necessary to carry in stock for maintaining such trucks.

Having thus set forth the nature of the invention what is claimed herein is:

1. In a locomotive engine, the combination,'with main-frames, and auxiliary framebars extended backwardly from such mainframes, of a radial truck-frame pivoted by suitable joint to the main-frame and having journal-bearings for a single axle and truck- .wheels, vertical sockets supported by the auxiliary frame-bars rigidly above the journalbearings with a spring-bearingblock movable in each of such sockets and a spring supported by such bearing-block, and the foot of each bearing-block being fitted to rest upon the top of one of the journal bearings, whereby the radial truck may positions beneath the springs, and the vertical movement of the journal-bearings be transmitted to the springs in all the said positions.

2.
